Answer:
V = 825
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The radius is 1/2 d = 1/2 (10) =5
Using 3 for pi
V = 3 ( 5)^2 * 11
V = 825
Answer:
r = 6cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
36 pi = pi r^2
Divide each side by pi
36 pi/pi = pi r^2/ pi
36 = r^2
Take the square root of each side
sqrt(36) = sqrt(r^2)
6 =r
The radius is 6 cm
r = 6cm
Given:
The sequence is -8, -12, -16.
To find:
The nth and 52th term of the given sequence.
Solution:
We have,
-8, -12, -16
It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is




The nth term of an AP is

Where, a is first term and d is common difference.
Putting a=-8 and d=-4, we get



Putting n=52, we get



Therefore, the equation for the nth term of the given sequence is
and the 52nd term of the sequence is -212.
Answer: B
Step-by-step explanation: The answer is B because it explains that H is the amount of hours. The last option doesn't have H included in the equation. Secondly. You want to find the total so you'll end up having an addition equation.
Therefore your answer is, c=45h + 95
Answer: 113.0cm²
Step-by-step explanation:
The surface area if a square is calculated as:
= 4πr²
where, radius = 3cm
Surface area = 4πr²
= 4 × 3.14 × 3²
= 4 × 3.14 × 9
= 113.04
= 113.0cm²
Therefore, the surface area is 113.0cm²
